Improving the industrial safety of hazardous production facilities operating in the North requires comprehensive consideration of the impact of natural and climatic factors specific to this area on risk parameters. Low temperatures and abnormal weather conditions of the North have a significant impact on both the frequency of accidents and the development of accidents. Abnormal weather conditions in the North are characterized by powerful temperature inversions that occur during anticyclone due to the emission of permafrost soil at extremely low ambient temperatures, and air stagnation conditions. The article presents an assessment of the risk of an accident in the event of a gas leak on the above-ground sections of the gas pipeline, taking into account abnormal weather conditions in the North. A model for assessing the potential risk has been developed taking into account abnormal weather conditions in the North. The potential and individual risk in the event of an explosion of a cloud of a gas-air mixture of methane in an open area was assessed.

The influence of operating conditions, design and circuit design features of avionics equipment has been analyzed, a mathematical model of failure rate has been developed taking into account the initial level, the rate of their growth and the threshold value of operating time for failure.
